--- Comment #7 from Harald Sitter <sitter at kde.org> ---
Right, so I *think* I've found it happening, but it's not really drkonqi's
fault. What likely happens is that GIO is being used by something (in my case
discover) and GIO will trip over a filedescriptor that was closed by KCrash
before drkonqi starts. GIO has a forced fatality attached to this so
essentially plasmashell crashes while we are trying to trace the crash. I've
not really found an easy way to prevent this. 

Possibly coordinate closing with drkonqi may prevent this sort of problem. I.e.
since we now have a socket from kcrash to drkonqi we could have drkonqi tell
kcrash when it SIGSTOP'ed the process, at this point kcrash can safely close
the file descriptors without risking that a still running thread will fall over
the closed FD.
Alas, I don't really know enough about this, or even if there is a reason that
the FDs are closed before starting drkonqi.
